I recently posted here about troubles with my garage door. I got some great advice, and found the issue to be a disconnected wire. However, a few weeks later and I have a new issue. The door, a metal rolling door, goes down nearly all the way, but then stops about a foot from the ground and then reverses. Not every time, but frequently. I came out the other morning to find I'd left the garage wide open all night. :(
When I had my issues a few weeks ago, I took the time to plumb the tracks as much as possible and lubricate most of the joints and rollers with a silicone lubricant, so I'm surprised to hear a high- pitched squeak as the door goes down. Is a silicone-based lubricant not a good garage door lubricant? Are there other possible scenarios for why the door is reversing when it's almost closed?
Thanks.
